Find the second derivative, (f”(x))
Set (f”(x)=0) and solve for critical candidates
Check where (f”(x)) is undefined
Test the sign of (f”(x)) on intervals around each candidate
Confirm a point of inflection only if (f”(x)) changes sign
Find the corresponding (y)-value by evaluating (f(x))
Write the inflection point as ((x, f(x)))
